Modular UPS
Hot-swappable power modules that grow with hall releases and allow module-level service while the protected bus stays online-ideal for phased data-centre expansion.
UPS architectures we engineer
Select form factor and redundancy to match white space, maintenance doctrine, and growth-without locking the facility into a dead-end frame or an unserviceable battery room.
Enterprise UPS frames
Proven high-efficiency platforms for corporate, healthcare, and finance facilities that need clear operator workflows, documented transfers, and multi-year spare strategies.
High-density designs
Elevated kW per footprint to free white space for IT or process equipment while supporting rising rack and line loads without premature room rebuilds.
Lithium & VRLA strategies
Chemistry, runtime, and thermal packages chosen for cycle life, footprint, fire strategy, and total cost of ownership-not a single default battery SKU.
Topology & bypass
From single UPS rooms to 2N campus chains
We help owners and EPCs define N+1 or 2N paths, static and maintenance bypass behaviour, and distribution coordination so planned work never becomes the outage root cause.
Where UPS specification is non-negotiable
UPS is the heart of a critical power chain. These environments are where Trident systems are most often engineered into the single-line.
Topology, modules, and bypass philosophy
Modular UPS platforms earn their place when phased hall growth, hot-swap service, and right-sized capital matter; enterprise frames remain appropriate for fixed loads and standardized operator workflows. Trident sizes both against N+1 or 2N path independence-not module marketing density alone.
Static and maintenance bypass behaviour is defined with distribution coordination so planned work never becomes the outage that was supposed to be impossible. True 2N requires electrical segregation through boards and batteries, not merely two frames sharing a vulnerability.
Battery chemistry and cutover method
Lithium and VRLA strategies are chosen for footprint, cycle life, thermal design, fire case, and total cost of ownership. Runtime covers generator acceptance plus margin-not arbitrary marketing minutes-and BESS extension is considered only when hierarchy is explicit.
Live cutovers succeed through method statements that freeze load priorities, validate bypass capacity, and define abort criteria. Improvisation on the floor is rejected as an acceptance strategy.
Efficiency modes under real disturbance history
Eco or high-efficiency modes can deliver energy savings when transfer behaviour is proven for the site’s load mix and utility quality. Double-conversion remains default where waveform sensitivity or contractual availability leave no tolerance-mode policy follows disturbance data, not energy marketing.
UPS engineering FAQs
Practical answers for consultants and operators sizing modules, batteries, and cutover strategy.
Runtime should cover the gap until generators are ready and stable, plus margin for start failures and sequential loading-not an arbitrary marketing minute count. For many data halls that means bridging to genset acceptance; for healthcare it may include code-driven emergency durations; for process lines it may mean finishing a controlled stop. We size autonomy against generator start reliability, load steps, and whether BESS will extend the window.
Lithium often wins on footprint, cycle life, and predictable state-of-health telemetry when thermal management and fire strategy are designed in. VRLA remains appropriate where capital, ambient conditions, or existing room infrastructure favour flooded or sealed lead-acid with a clear replacement cycle. The decision is TCO plus safety case, not chemistry fashion.
Through method statements that freeze load priorities, validate bypass capacity, stage temporary or parallel paths where needed, and define abort criteria. Live cutovers succeed when electrical, controls, and operations rehearse the sequence-not when equipment arrives and the team improvises on the floor.
High-efficiency or eco modes can deliver meaningful energy savings when transfer behaviour under disturbance is proven for your load mix and utility quality. Double-conversion remains the default where waveform sensitivity, transfer risk, or contractual availability leave no tolerance. We recommend mode policy only after reviewing disturbance history and transfer test data.
Yes-when A and B paths are electrically independent through distribution and each path has its own module set, batteries, and bypass strategy. Modular does not automatically equal redundant; topology and physical segregation still define availability.
